Description

Technical Field

[0001] This application relates to the field of batteries, and more specifically, to a coating assembly and coating equipment. Background Technology

[0002] With the continuous advancement of battery technology, various new energy industries using batteries as energy storage devices have developed rapidly. The development of battery technology must consider multiple design factors simultaneously, such as performance parameters like energy density, cycle life, discharge capacity, and charge / discharge rate. Additionally, battery processing efficiency must also be considered. During battery processing, sealing or fixing is achieved through adhesive coating; therefore, the efficiency of adhesive coating directly affects the overall battery processing efficiency. Utility Model Content

[0003] This application provides a coating component and coating equipment that can improve the efficiency and quality of coating during battery processing.

[0004] In a first aspect, this application provides an adhesive application assembly, comprising: an adhesive dispensing mechanism for applying adhesive to a product to be coated; and a visual inspection mechanism for inspecting the adhesive application quality in the coated area; the adhesive dispensing mechanism and the visual inspection mechanism are fixed relative to each other, and the visual inspection mechanism and the adhesive dispensing mechanism are arranged sequentially along the adhesive application direction.

[0005] In the technical solution of this application embodiment, on the one hand, both the vision inspection mechanism and the dispensing mechanism are set on the dispensing mechanism, and their positions are relatively fixed. During the dispensing process, the vision inspection mechanism can detect the glue immediately after the dispensing mechanism completes partial dispensing. It can almost simultaneously detect the glue shape and size online. Once the glue does not meet the requirements, it can be maintained immediately, avoiding rework due to delayed detection. Therefore, it can effectively improve the glue application efficiency and quality. At the same time, the vision inspection mechanism and the dispensing mechanism are integrated on the glue application assembly, which can reduce the use of processing space and save glue application costs. On the other hand, the glue application assembly is controlled by the first robotic arm to apply glue to the product to be glued, which can realize automatic glue application. The vision inspection mechanism and the dispensing mechanism are set sequentially along the glue application direction. The dispensing mechanism is set in front of the vision inspection mechanism, which reduces the obstruction of the vision inspection mechanism when detecting the glue quality and improves the accuracy of the vision inspection mechanism in detecting the glue quality.

[0006] In some embodiments of the first aspect, the visual inspection mechanism includes a visual inspection unit and a light source plate; the light source plate is disposed on the side of the visual inspection unit near the product to be coated, the light source plate has a through hole, and the projection of the visual inspection unit on the light source plate along the thickness direction of the light source plate is located in the area of ​​the through hole.

[0007] In this embodiment, a light source board is positioned between the product to be coated and the vision inspection unit. The light from the light source board directly illuminates the surface of the coating area, enabling the vision inspection unit to capture a clear image. Furthermore, the light source board illuminates the coating area directly along its thickness direction, eliminating unnecessary shadows caused by unevenness on the coating surface, reducing interference with the vision inspection unit, improving image clarity, and thus enhancing the quality of the coating inspection.

[0008] In some embodiments of the first aspect, the vision detection unit includes a charge-coupled device (CCD).

[0009] In this embodiment, the CCD can detect very weak light with high resolution and fast response, thereby reading image data. By setting the CCD to detect the adhesive coating area 402, the adhesive coating quality requirements can be met, and the CCD can respond quickly to improve the adhesive coating efficiency.

[0010] In some embodiments of the first aspect, the dispensing mechanism includes a first colloid chamber, a second colloid chamber, a mixing chamber, a dispensing tube, and a nozzle; wherein the first colloid chamber and the second colloid chamber are respectively connected to the mixing chamber, one end of the dispensing tube is connected to the mixing chamber, and the other end of the dispensing tube is connected to the nozzle; the colloid in the first colloid chamber and the colloid in the second colloid chamber are mixed in the mixing chamber and discharged from the nozzle through the dispensing tube.

[0011] In this embodiment of the application, by automatically mixing different types of colloids, the adhesive performance of the colloids can be improved to a certain extent, which can meet the coating performance requirements of more products and improve the multi-dimensional performance of the entire coating equipment.

[0012] In some embodiments of the first aspect, the adhesive applicator further includes a nozzle positioning mechanism having a first positioning block, a second positioning block, and a positioning pin; wherein the first positioning block and the second positioning block are connected, the second positioning block has a through hole with the axial direction of the nozzle as the central axis, the nozzle is fixed in the through hole, and the side of the first positioning block near the positioning pin has a positioning hole, the positioning pin is inserted into the positioning hole, thereby positioning the height of the nozzle.

[0013] In this embodiment, by keeping the positions of the first and second positioning blocks relative to the adhesive application assembly fixed, and by allowing the positioning pin to be inserted into the positioning hole of the first positioning block, the nozzle positioning mechanism can maintain an accurate position. Inserting and fixing the nozzle into the through hole of the second positioning block determines the nozzle's installation position, ensuring an accurate installation height.

[0014] In some embodiments of the first aspect, the nozzle positioning mechanism further includes a positioning sensor located on the side of the first positioning block away from the positioning pin. The side of the first positioning block near the positioning sensor has a metal plate fixed to the first positioning block. The positioning sensor detects that the nozzle is installed in place by sensing the metal plate.

[0015] In this embodiment, a positioning sensor is used to automatically detect the installation position of the nozzle. On the one hand, this allows for quick detection of whether the nozzle is installed correctly, enabling timely response and improving the glue application efficiency of the glue application equipment. On the other hand, if an incorrect installation position is detected, an alarm can be triggered immediately for adjustment, thereby reducing glue application quality problems caused by improper nozzle positioning.

[0016] In some embodiments of the first aspect, the adhesive application assembly further includes an adhesive receiving mechanism, which includes an adhesive receiving box, a first moving mechanism, and a second moving mechanism; wherein the first moving mechanism is connected to the second moving mechanism, the adhesive receiving box is fixed to the second moving mechanism, the first moving mechanism moves relative to the adhesive application assembly along a first direction, and the second moving mechanism moves relative to the first moving mechanism along a second direction, the first direction being perpendicular to the second direction.

[0017] In this embodiment, the glue application component is equipped with a glue receiving mechanism, which enables the glue application equipment to receive the residual glue on the glue nozzle after the glue application is completed, preventing the residual glue from falling onto the product or other equipment, thereby improving the glue application quality to a certain extent.

[0018] In some embodiments of the first aspect, the product to be coated includes a battery device and a battery cell.

[0019] Secondly, this application provides an adhesive application device, comprising: a support for placing a product to be coated with adhesive; a first robotic arm disposed on one side of the support; and an adhesive application assembly according to the first aspect or any embodiment thereof, wherein the adhesive application assembly is connected to the first robotic arm, and the first robotic arm controls the adhesive application assembly to apply adhesive to the product to be coated with adhesive.

[0020] In some embodiments of the second aspect, the adhesive applicator further includes a weighing detection mechanism for measuring the weight of the adhesive to detect whether the dispensing mechanism is in normal operating condition.

[0021] In this embodiment, on the one hand, by automatically weighing the colloid through a weighing and detection mechanism, the coating quality of the coating equipment can be maintained stably, and the accuracy of automatic coating can be improved; on the other hand, different required dispensing amounts can be set for different products to be coated, thereby improving the compatibility of the coating equipment with different products.

[0022] In some embodiments of the second aspect, the adhesive applicator further includes a fixing component comprising a tray and a cylinder, the tray being placed on the support, the product to be coated being fixed on the tray, the cylinder being located on the side of the tray away from the product to be coated, and the cylinder moving along the thickness direction of the tray to separate or contact the tray with the support.

[0023] In this embodiment, the cylinder moves back and forth along the thickness direction of the tray to separate and contact the tray with the support, which can automatically complete the fixing operation of the product to be glued, reduce labor costs, and improve the glue application efficiency of the glue application equipment.

[0024] In some embodiments of the second aspect, a conveyor belt is provided on the support, and the pallet is placed on the conveyor belt; the cylinder moves toward the pallet, such that the pallet is connected to the cylinder and separated from the conveyor belt on the support; and / or, the cylinder moves away from the pallet, such that the pallet contacts the conveyor belt on the support and separates from the cylinder, so that the pallet moves with the conveyor belt.

[0025] In this embodiment, the product to be coated on the pallet can move along the conveyor belt with the pallet. The product to be coated can be moved from other stations to the coating station, and from the coating station to other processing stations, thereby improving the automation level of the coating equipment.

[0026] In some embodiments of the second aspect, a second stop and a first stop are sequentially provided on the support along the direction of movement of the conveyor belt; the first stop is movable along the thickness direction of the tray to prevent the tray from moving with the conveyor belt, and the second stop is used to prevent the tray from rebounding after it stops moving with the conveyor belt.

[0027] In this embodiment, the first stop and the second stop can quickly stop the tray so that the cylinder can fix the tray and separate the tray from the conveyor belt, thereby enabling the gluing assembly to apply glue to the product to be glued.

[0028] In some embodiments of the second aspect, the distance between the first stop and the second stop along the direction of movement of the conveyor belt is greater than or equal to the size of the pallet along the direction of movement of the conveyor belt, and less than a first threshold.

[0029] In this embodiment, by setting the distance between the first stop and the second stop along the conveyor belt's moving direction to be greater than or equal to the pallet's dimension along that direction, the pallet can be stopped promptly when it reaches the target position. The first threshold can be slightly greater than the pallet's dimension along the conveyor belt's moving direction, so that after the pallet is blocked by the first stop, the second stop can prevent the pallet from bouncing back too far, and can quickly stop the pallet at the target position.

[0030] In some embodiments of the second aspect, the adhesive coating equipment further includes a second robotic arm and a plasma cleaning mechanism. The second robotic arm is disposed on one side of the support, and the plasma cleaning mechanism is connected to the second robotic arm.

[0031] In this embodiment, the plasma cleaning mechanism removes dust, oil, moisture, and other impurities from the surface to be coated, improving the adhesive's bonding performance. Furthermore, cleaning the surface ensures good contact between the adhesive and the product being coated, thereby increasing bond strength and improving coating quality.

[0032] In some embodiments of the second aspect, the second robotic arm and the first robotic arm are sequentially arranged on one side of the support along the direction of movement of the conveyor belt.

[0033] In this embodiment, the tray moving with the conveyor belt carries the product to be coated through a plasma cleaning mechanism and a coating assembly. The product is first cleaned at the plasma cleaning mechanism, and then coated with adhesive at the coating assembly. The coating equipment can directly transfer the cleaned product to the coating assembly for coating, eliminating the need for manual operation and saving time and labor costs while improving the coating efficiency.

[0034] In some embodiments of the second aspect, the fixing component includes a first fixing component and a second fixing component, the first fixing component being disposed on the support near the first robotic arm, and the second fixing component being disposed on the support near the second robotic arm.

[0035] In this embodiment, fixed components are installed at the locations where the product to be coated is cleaned and coated, which can automatically complete the cleaning and coating of the product, improve the automation level of the coating equipment, and further improve the coating efficiency of the coating equipment.

[0066] As an example, the enclosure may include a first enclosure and a second enclosure. The first enclosure and the second enclosure are fastened together to form a closed space inside the enclosure to house the individual battery cells. Here, "closed" refers to covering or closing, and can be either sealed or unsealed. The first enclosure may be a top cover or a bottom plate.

[0067] As an example, the enclosure may include a top cover, a frame, and a bottom plate. The top cover and bottom plate are connected to the frame, creating an enclosed space inside the enclosure to house the individual battery cells.

[0069] The technical solutions described in the embodiments of this application are applicable to various electrical devices that use individual battery cells, such as mobile phones, portable devices, laptops, electric vehicles, electric toys, power tools, vehicles, ships, and spacecraft. For example, spacecraft include airplanes, rockets, space shuttles, and spacecraft.

[0070] Currently, judging from market trends, the application of power batteries is becoming increasingly widespread. Power batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also extensively used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. With the continuous expansion of power battery applications, market demand is also constantly increasing.

[0071] The development of battery technology must consider multiple design factors simultaneously, such as performance parameters like energy density, cycle life, discharge capacity, and charge / discharge rate. Additionally, it's crucial to consider battery processing efficiency and yield. For instance, improving the assembly efficiency between battery components can enhance processing efficiency. During battery manufacturing, adhesive application is typically required for relevant components. For example, the mating surfaces between the upper and lower casings of a battery pack usually require adhesive to ensure good sealing. In the encapsulation process of power batteries, adhesive application ensures tight bonding of components such as individual cells, side plates, and end plates. During adhesive application, the adhesive shape and size must be checked to meet specific quality standards. Therefore, how to quickly complete the adhesive application process and effectively improve its efficiency and quality to further enhance battery processing efficiency is a critical issue in the battery industry.

[0072] Therefore, the adhesive application assembly of this application embodiment can solve the above-mentioned problems. The adhesive application assembly of this application embodiment includes an adhesive dispensing mechanism and a vision inspection mechanism. The adhesive dispensing mechanism is used to apply adhesive to the product to be coated; the vision inspection mechanism is used to detect the coating quality of the coating area; the adhesive dispensing mechanism and the vision inspection mechanism are fixed relative to each other, and the vision inspection mechanism and the adhesive dispensing mechanism are arranged sequentially along the coating direction. On the one hand, both the vision inspection mechanism and the dispensing mechanism are located on the dispensing mechanism, and their positions are relatively fixed. During the dispensing process, the vision inspection mechanism can detect the glue immediately after the dispensing mechanism completes partial dispensing, almost simultaneously detecting the glue shape and size online. If the glue does not meet the requirements, it can be maintained immediately, avoiding rework due to delayed detection. Therefore, it can effectively improve the glue application efficiency and quality. At the same time, integrating the vision inspection mechanism and the dispensing mechanism into the glue application assembly can reduce the use of processing space and save glue application costs. On the other hand, the glue application assembly is controlled by the first robotic arm to apply glue to the product to be glued, which can realize automatic glue application. The vision inspection mechanism and the dispensing mechanism are arranged sequentially along the glue application direction, with the dispensing mechanism placed before the vision inspection mechanism. This reduces the obstruction of the vision inspection mechanism when detecting the glue quality, improving the accuracy of the vision inspection mechanism in detecting the glue quality.

[0073] It should be understood that the adhesive application assembly of this application embodiment can be used to apply adhesive to the adhesive application area of ​​a product to be coated. The product to be coated can include any device requiring adhesive application. For example, the product to be coated can include a battery device, such as the battery housing, and the adhesive application area can include the location between the upper and lower housings where adhesive is needed. As another example, the product to be coated can also include individual battery cells and a base plate or side plate, and the adhesive application area can include the location between the individual battery cells and the base plate, or between the individual battery cells and the side plate, etc., where adhesive is needed. However, this application embodiment is not limited to these examples.

[0074] Figure 1 A schematic diagram of the structure of the product 40 to be coated with adhesive according to an embodiment of this application is shown; Figure 2 A schematic diagram of the adhesive application assembly according to an embodiment of this application is shown. Figure 1 and Figure 2 As shown, the adhesive application assembly 30 in this embodiment may include: an adhesive dispensing mechanism 31 for applying adhesive to the product 40 to be coated; and a visual inspection mechanism 32 for detecting the adhesive application quality of the coating area 402. The adhesive dispensing mechanism 31 and the visual inspection mechanism 32 are fixed relative to each other, and the visual inspection mechanism 32 and the adhesive dispensing mechanism 31 are arranged sequentially along the adhesive application direction.

[0075] It should be understood that the product 40 to be coated in this embodiment can be any component. The product 40 is placed on a support, and its coating surface 401 can be the side of the product 40 facing away from the support and close to the coating assembly 30. The coating direction can be any trajectory direction on the coating surface 401. For example, Figure 1 The product 40 to be coated with adhesive shown can be the lower casing of a battery pack, and the upper surface of the lower casing can be the adhesive-coating surface 401. On the adhesive-coating surface 401, the adhesive dispensing mechanism 31 can apply adhesive to the product 40 in a clockwise direction or a counterclockwise direction. Alternatively, the product 40 can also be a side panel of a battery pack, and the surface of the side panel near the outside of the battery pack can be the adhesive-coating surface 401. Adhesive can be applied to the adhesive-coating surface 401 in a clockwise or counterclockwise direction. The application path can be from the outer periphery of the adhesive-coating surface 401 towards the center of symmetry, or from the center of symmetry towards the outer periphery, following a "U"-shaped path. The application trajectory can also be an "S"-shaped route, etc., but the embodiments of this application are not limited to these.

[0076] In this embodiment, the adhesive application assembly 30 may include an adhesive dispensing mechanism 31 and a vision inspection mechanism 32. The adhesive dispensing mechanism 31 is used to dispense adhesive onto the product 40 to be coated. The vision inspection mechanism 32 is used to inspect the adhesive application quality of the coating area 402. After the adhesive dispensing mechanism 31 completes the adhesive application onto the surface 401 to be coated, the surface 401 to be coated, as the coating area 402, is subjected to quality inspection by the vision inspection mechanism 32. The vision inspection mechanism 32 can detect the adhesive trajectory, adhesive size, etc., to determine whether the adhesive application meets the requirements. If the requirements are met, the remaining surface to be coated is coated; if the requirements are not met, the adhesive application abnormality can be detected in time, thereby enabling timely intervention and adjustment, reducing the need for rework due to substandard adhesive application quality, and improving adhesive application efficiency.

[0077] It should be understood that the dispensing mechanism 31 and the vision inspection mechanism 32 are relatively fixed, and the vision inspection mechanism 32 and the dispensing mechanism 31 are arranged sequentially along the dispensing direction. That is, both the dispensing mechanism 31 and the vision inspection mechanism 32 are fixed on the dispensing assembly 30, and their positions remain relatively fixed.

[0078] The direction of adhesive application can be Figure 2As shown in the X1 direction, during the glue application process of the glue application assembly 30, the glue dispensing mechanism 31 and the vision inspection mechanism 32 move together along the glue application direction X1. The vision inspection mechanism 32 and the glue dispensing mechanism 31 are arranged sequentially along the glue application direction, that is, in the glue application direction X1, the glue dispensing mechanism 31 is in front and the vision inspection mechanism 32 is behind. After the glue dispensing mechanism 31 completes the glue application at the current position, it continues to move along the glue application direction. The vision inspection mechanism 32, which moves later, reaches the area where the glue dispensing mechanism 31 has just completed the glue application and performs inspection, thereby detecting the glue application quality in real time. Both the glue dispensing mechanism 31 and the vision inspection mechanism 32 are set on the glue application assembly 30, and the distance between them is very small. Therefore, when the glue dispensing mechanism 31 completes the glue application to the current area to be glued, the vision inspection mechanism 32 can almost simultaneously perform glue quality inspection on that area.

[0079] On the one hand, both the vision inspection mechanism and the dispensing mechanism are located on the dispensing mechanism, and their positions are relatively fixed. During the dispensing process, the vision inspection mechanism can detect the glue immediately after the dispensing mechanism completes partial dispensing, almost simultaneously detecting the glue shape and size online. If the glue does not meet the requirements, it can be maintained immediately, avoiding rework due to delayed detection. Therefore, it can effectively improve the glue application efficiency and quality. At the same time, the integration of the vision inspection mechanism and the dispensing mechanism on the glue application assembly can reduce the use of processing space and save glue application costs. On the other hand, the glue application assembly is controlled by the first robotic arm to apply glue to the product to be glued, which can realize automatic glue application. The vision inspection mechanism and the dispensing mechanism are arranged sequentially along the glue application direction, with the dispensing mechanism placed before the vision inspection mechanism. This reduces the obstruction of the vision inspection mechanism when detecting the glue quality and improves the accuracy of the vision inspection mechanism in detecting the glue quality.

[0080] Figure 3 A side view of the adhesive application assembly according to an embodiment of this application is shown. For example, the... Figure 3 It shows Figure 2 A side view of the adhesive application assembly 30 along the X2 direction; Figure 4 A bottom view of the adhesive application assembly according to an embodiment of this application is shown, for example, Figure 4 It shows Figure 2 The diagram shows a bottom view of the adhesive application assembly 30.

[0081] In some embodiments, such as Figure 3 and Figure 4As shown, the visual inspection mechanism 32 may include a visual inspection unit 321 and a light source plate 322. The light source plate 322 is disposed on the side of the visual inspection unit 321 near the product 40 to be coated with adhesive. The light source plate 322 has a first through hole 3221. The projection of the visual inspection unit 321 onto the light source plate 322 along its thickness direction is located within the through hole area. The light source plate 322 is disposed between the product 40 to be coated with adhesive and the visual inspection unit 321. The light from the light source plate 322 directly illuminates the surface of the coating area 402, enabling the visual inspection unit 321 to capture a clear image. In addition, the light source plate 322 directly illuminates the surface of the coating area 402 along its thickness direction, thereby eliminating some unnecessary shadows caused by unevenness of the coating surface, reducing interference with the visual inspection unit 321, improving image clarity, and thus improving the quality of adhesive coating inspection.

[0082] It should be understood that the first through-hole 3221 on the light source plate 322 enables the vision inspection unit 321 to pass through the first through-hole 3221 to detect the size and trajectory of the adhesive on the adhesive application area 402, thereby detecting the adhesive application quality of the current adhesive application area. The position of the first through-hole 3221 can be set in any area on the light source plate 322, as long as the vision inspection unit 321 can be aligned with the first through-hole 3221 to detect the adhesive application area 402. For example, the first through-hole 3221 can be set at the geometric center of the light source plate 322, and the light source plate 322 can illuminate the adhesive application area 402 from all four sides, thereby providing the vision inspection unit 321 with a clearer picture of the shape and size of the adhesive, thus improving the adhesive application detection quality. For example, the first through hole 3221 can also be set at a position on the light source plate 322 near the glue dispensing mechanism 31, thereby reducing the distance between the vision inspection unit 321 and the glue dispensing mechanism 31, so that the vision inspection unit 321 can detect the glue quality of the current glued area in a very short time after the glue dispensing mechanism 31 completes the glue application, further improving the glue application efficiency of the glue application equipment.

[0083] It should be understood that the projection of the visual inspection unit 321 onto the light source plate 322 along the thickness direction of the light source plate 322 is located within the area of ​​the first through hole 3221. That is, the orthographic projection of the visual inspection unit 321 onto the light source plate 322 should be entirely mapped into the area where the first through hole 3221 is located. This can be understood as the area of ​​the orthographic projection of the visual inspection unit onto the light source plate 322 being less than or equal to the area of ​​the region of the light source plate 322 occupied by the first through hole 3221. The specific location of the projection of the visual inspection unit 321 onto the light source plate 322 along the thickness direction of the light source plate 322 within the area of ​​the first through hole 3221 is not limited. For example, the projection can be located closer to the dispensing mechanism 31 within the area of ​​the first through hole 3221, or it can be located further away from the dispensing mechanism 31 within the area of ​​the first through hole 3221. Furthermore, the geometric center of the projection can coincide with the geometric center of the first through hole 3221, meaning the projection is located in the very center region of the through hole.

[0084] Additionally, the vision inspection unit 321 can be an image sensor, including a charge-coupled device (CCD), a metal-oxide-semiconductor (CMOS) device, a back-illuminated CMOS, and a stacked CMOS, etc. In some embodiments, the vision inspection unit 321 may include a charge-coupled device (CCD). A CCD can detect very weak light, has high resolution, and can respond quickly to read image data. By setting a CCD to perform adhesive coating detection on the coating area 402, good coating quality requirements can be met, and the CCD's fast response improves the coating efficiency of the coating equipment.

[0085] In some embodiments, such as Figure 5 As shown, Figure 5 A partial structural schematic diagram of the adhesive application assembly according to an embodiment of this application is shown. For example, the... Figure 5 It shows Figure 2 The diagram shows a partial structural schematic of the adhesive application assembly 30, including the adhesive dispensing mechanism 31. (See attached diagram.) Figure 5As shown, the dispensing mechanism 31 may include a first colloid chamber 311, a second colloid chamber 312, a mixing chamber 313, a dispensing pipe 314, and a nozzle 315. The first colloid chamber 311 and the second colloid chamber 312 are respectively connected to the mixing chamber 313. One end of the dispensing pipe 314 is connected to the mixing chamber 313, and the other end is connected to the nozzle 315. The colloid in the first colloid chamber 311 and the colloid in the second colloid chamber 312 are mixed in the mixing chamber 313 and discharged from the nozzle 315 through the dispensing pipe 314. It should be understood that the number of first colloid chambers 311 and second colloid chambers 312 can be one or more. The colloid contained in the first colloid chambers 311 and the second colloid chambers 312 can be the same type of colloid or different types of colloids. The number of colloid chambers and the type of colloid contained can be flexibly set and changed according to the type of colloid required for the actual product to be coated. In this embodiment, the mixing of two different types of colloids is used as an example for description.

[0086] It should be understood that the first colloid cavity 311 and the second colloid cavity 312 can be connected to the mixing cavity 313 respectively. That is, the first colloid cavity 311 and the second colloid cavity 312 are respectively connected to the mixing cavity, so that the colloid in the first colloid cavity 311 can enter the mixing cavity 313. Similarly, the colloid in the second colloid cavity 312 can also enter the mixing cavity 313. The mixing cavity 313 can mix the two colloids from the first colloid cavity 311 and the second colloid cavity 312 respectively, thereby obtaining the type of colloid required for the product to be coated 40. In addition to having a portion that communicates with the first colloid cavity 311 and the second colloid cavity 312, the mixing cavity 313 also has a portion that communicates with the dispensing pipe 314, so that the colloid mixed in the mixing cavity 313 can pass through the dispensing pipe 314 and be discharged from the nozzle 315 connected to the dispensing pipe 314, thereby realizing the coating of the current coating area 402 of the product to be coated 40. By automatically mixing different types of colloids, the adhesive properties of the colloids can be improved to a certain extent, which can meet the coating performance requirements of more products and improve the multi-faceted performance of coating equipment.

[0087] In some embodiments, the mixing chamber 313 may contain a stirrer that can stir the colloids from the first colloid chamber 311 and the second colloid chamber 312 to ensure that the colloids are fully mixed so as to discharge the required colloids for the product to be coated 40.

[0088] In some embodiments, such as Figure 2 As shown, the glue application assembly 30 may also include a glue nozzle positioning mechanism 33. For example... Figure 6 and Figure 7 As shown, Figure 6 A schematic diagram of the nozzle positioning mechanism according to an embodiment of this application is shown. For example, the... Figure 6 It shows Figure 2 A schematic diagram of the nozzle positioning mechanism 33 in the glue application assembly 30 shown; Figure 7 This diagram shows a front view of the nozzle positioning mechanism according to an embodiment of the present application. For example, the... Figure 7 It shows Figure 2 The diagram shows a front view of the nozzle positioning mechanism 33 in the adhesive application assembly 30 along the X1 direction. Figures 5 to 7 As shown, the nozzle positioning mechanism 33 has a first positioning block 331, a second positioning block 332, and a positioning pin 333. The first positioning block 331 and the second positioning block 332 are connected. The second positioning block 332 has a second through hole 3321 with the axial direction of the nozzle 315 as its central axis. The nozzle 315 is fixed in the second through hole 3321. The first positioning block 331 has a positioning hole 3310 on the side near the positioning pin 333. The positioning pin 333 is inserted into the positioning hole 3310, thereby positioning the height of the nozzle 315.

[0089] In this embodiment, the first positioning block 331 is fixed to the adhesive application assembly 30, and the second positioning block 332 is connected to the first positioning block 331 and is also fixed to the adhesive application assembly 30. It should be understood that the positioning pin 333 has a fixed portion 3331 and a movable portion 3332. The fixed portion 3331 is also fixed to the adhesive application assembly 30, and the movable portion 3332 can move axially within and along the through hole of the fixed portion 3331. The positioning pin 333 is located on one side of the first positioning block 331, and the side of the first positioning block 331 near the positioning pin 333 has a positioning hole 3310, allowing the positioning pin 333 to be inserted into the positioning hole 3310. By maintaining a relatively fixed position between the first positioning block 331 and the second positioning block 332 and the adhesive application assembly 30, and by allowing the positioning pin 333 to be inserted into the positioning hole 3310 of the first positioning block 331, the nozzle positioning mechanism 33 can be kept in an accurate position. By inserting and fixing the nozzle 315 into the second through hole 3321 of the second positioning block 332, the correct installation position of the nozzle 315 can be determined, so that the nozzle 315 has an accurate installation height.

[0090] The first positioning block 331 can be a single integrated structure, or it can be composed of different structures fixed together. For example... Figure 6As shown, in some embodiments, the first positioning block includes a fixed base block 3311, a positioning base block 3312, and a connecting block 3313. The fixed base block 3311 is fixed to the adhesive application assembly 30, and both the positioning base block 3312 and the connecting block 3313 are fixed to the fixed base block 3311. The positioning base block 3312 is located on the side of the fixed base block 3311 closest to the positioning pin 333. A positioning hole 3310 is provided on the side of the positioning base block 3312 closest to the positioning pin 333. The axis of the movable part 3332 of the positioning pin 333 coincides with the axis of the positioning hole 3310, allowing the movable part 3332 of the positioning pin to be inserted into the positioning hole 3310 to ensure the first positioning block 331 is properly installed. The connecting block 3313 connects the fixed base block 3311 and the second positioning block 332, ensuring the second positioning block 332 has a fixed position relative to the adhesive application assembly 30, thereby providing an accurate installation position for the nozzle 315. In some embodiments, the positioning base block 3312 and the fixing base block 3311, the connecting block 3313 and the fixing base block 3311, and the fixing base block 3311 and the adhesive application assembly can all be fixed by bolts to facilitate the disassembly and installation of different components.

[0091] In some embodiments, during the replacement of the nozzle, the positioning pin 333 can first be pulled out of the positioning hole 3310; then, the first positioning block 331 is removed from the glue application assembly 30 and moved from top to bottom along the axial direction of the nozzle 315. At this time, the second positioning block 332 moves with the first positioning block 331, thereby separating the nozzle 315 from the second through hole 3321 on the second positioning block 332; then, the nozzle 315 is removed from the glue dispensing mechanism 31 and another nozzle is installed at the end of the glue discharge pipe 314 away from the mixing chamber 313; finally, the removed first positioning block 331 and second positioning block 332 are reinstalled and fixed on the glue application assembly 30 in the reverse process of disassembly, and the positioning pin 333 is inserted into the positioning hole 3310, indicating that the replaced nozzle has been successfully installed.

[0092] In some embodiments, such as Figure 5 As shown, the nozzle positioning mechanism 33 also has a positioning sensor 334. The positioning sensor 334 is located on the side of the first positioning block 331 away from the positioning pin 333. The side of the first positioning block 331 near the positioning sensor 334 has a metal piece 3314. The metal piece 3314 is fixed on the first positioning block 331. The positioning sensor 334 detects that the nozzle 315 is installed in place by sensing the metal piece 3314.

[0093] It should be understood that the metal piece 3314 is fixed to the first positioning block 331, meaning the position of the metal piece 3314 and the first positioning block 331 is relatively fixed. When the first positioning block 331 is fixed to the adhesive application assembly 30, and the positioning pin 333 can be inserted into the positioning hole 3310, it indicates that the first positioning block 331 is currently in the correct position, the nozzle 315 is installed in place, and the metal piece 3314 will move with the first positioning block 331 to the target area. The positioning sensor 334 can thus sense the metal piece 3314 in the target area, thereby automatically detecting the installation position of the nozzle 315. However, if the nozzle 315 is not installed in place, the positioning sensor 334 cannot detect the metal piece 3314 in the target area, and the positioning sensor 334 will promptly sound an alarm to prevent incorrect installation of the nozzle 315 from affecting the adhesive application quality.

[0094] By setting up positioning sensors to automatically detect the installation position of the nozzle, on the one hand, it can quickly detect whether the installation position of the nozzle is correct and respond in a timely manner, thereby improving the glue application efficiency of the glue application equipment; on the other hand, if an incorrect installation position is detected, an alarm can be set up immediately for adjustment, thereby reducing glue application quality problems caused by improper nozzle positioning.

[0095] In some embodiments, such as Figure 2 As shown, the adhesive application assembly 30 may further include an adhesive receiving mechanism 34. For example... Figure 8 and Figure 9 As shown, Figure 8 A schematic diagram of the adhesive bonding mechanism according to an embodiment of this application is shown. For example, the... Figure 8 As shown Figure 2 A schematic diagram of the adhesive receiving mechanism 34 in the adhesive application assembly 30 shown;

[0096] Figure 9 A side view of the adhesive bonding mechanism according to an embodiment of this application is shown. For example, the... Figure 9 As shown Figure 8 The shown diagram is a side view of the adhesive bonding mechanism 34 along the direction perpendicular to X2. Figure 8 and Figure 9 As shown, the adhesive dispensing mechanism 34 includes an adhesive receiving box 341, a first moving mechanism 342, and a second moving mechanism 343. The first moving mechanism 342 is connected to the second moving mechanism 343, and the adhesive receiving box 341 is fixed to the second moving mechanism 343. The first moving mechanism 342 moves relative to the adhesive application assembly 30 along a first direction, and the second moving mechanism 343 moves relative to the first moving mechanism 342 along a second direction. The first direction is perpendicular to the second direction. It should be understood that the second direction can be... Figure 2 In the X2 direction, the first direction can be the axial direction of the nozzle 315, that is, the first direction is perpendicular to both the X1 and X2 directions.

[0097] In some embodiments, the first moving mechanism 342 has a slide rail on the side near the adhesive application assembly 30, and the adhesive application assembly 30 is connected to the slide rail of the first moving mechanism 342 via a slider; and / or, the adhesive application assembly 30 has a slide rail on the side near the first moving mechanism 342, and the first moving mechanism 342 is connected to the slide rail of the adhesive application assembly 30 via a slider, that is, the first moving mechanism 342 and the adhesive application assembly 30 can be slidably connected, allowing the first moving mechanism 342 to move relative to the adhesive application assembly 30 in the axial direction of the nozzle 315. The second moving mechanism 343 has a slide rail on the side near the first moving mechanism 342, and the first moving mechanism 342 is connected to the slide rail of the second moving mechanism 343 via a slider; and / or, the first moving mechanism 342 has a slide rail on the side near the second moving mechanism 343, and the second moving mechanism 343 is connected to the slide rail of the first moving mechanism 342 via a slider, that is, the second moving mechanism 343 and the first moving mechanism 342 can be slidably connected, allowing the second moving mechanism 343 to move relative to the first moving mechanism 342 in the X2 direction.

[0098] It should be understood that the movement of the first moving mechanism 342 and the second moving mechanism 343 in different directions can be automatically controlled in a variety of ways. For example, the movement of the first moving mechanism 342 on the glue application assembly 30 can be controlled by pneumatic drive, and the movement of the second moving mechanism 343 on the first moving mechanism 342 can also be controlled by pneumatic drive.

[0099] It should be understood that during the movement of the first moving mechanism 342 along the axial direction of the nozzle 315, the second moving mechanism 343 also moves along the axial direction of the nozzle 315 along with the first moving mechanism 342. During the process of applying glue to the product 40 from the nozzle, the first moving mechanism 342 drives the second moving mechanism 343 to move along the axial direction of the nozzle 315 to a position away from the product 40. This ensures that the distance between the glue receiving mechanism 34 and the product 40 in the axial direction of the nozzle 315 is greater than the distance between the nozzle 315 and the product 40, so that the glue receiving mechanism 34 does not interfere with the normal glue application of the nozzle 315. After the nozzle 315 completes one application, the first robotic arm 20 moves the glue application assembly 30 a certain distance away from the product, thereby causing the first moving mechanism 342 to move the second moving mechanism 343 towards the product, so that the glue receiving box 341 is positioned between the nozzle 315 and the product in the axial direction of the nozzle 315. Then, the second moving mechanism 343 drives the glue receiving box 341 to move closer to the glue nozzle 315 along the X2 direction, so that the projection of the glue nozzle 315 along its axial direction is located in the glue receiving box 341, so that the glue receiving box 341 catches the remaining glue after the glue nozzle 315 has finished applying the glue.

[0100] The glue application assembly 30 is equipped with a glue receiving mechanism 34, which enables the glue application assembly to receive the residual glue on the glue nozzle 315 after the glue application is completed, preventing the residual glue from falling onto the product or other equipment, thereby improving the glue application quality of the system to a certain extent.

[0101] According to some embodiments of this application, this application also provides an adhesive application device. Figure 10 A schematic diagram of the structure of an adhesive coating device according to an embodiment of this application is shown, for example, Figure 10 It shows including Figure 2 A schematic diagram of the adhesive application equipment 1 shown for the adhesive application assembly 30; Figure 11 A top view of the adhesive coating apparatus according to an embodiment of this application is shown, for example, Figure 11 It shows Figure 10 The diagram shows a top view of the adhesive application equipment 1 along the Z-direction. Figure 10 and Figure 11 As shown, the adhesive application device 1 in this application embodiment may include: a support 10 for placing the product 40 to be coated with adhesive; a first robotic arm 20 disposed on one side of the support 10; and an adhesive application component 30 as described in any of the above embodiments, the adhesive application component 30 being connected to the first robotic arm 20, the first robotic arm 20 controlling the adhesive application component 30 to apply adhesive to the product 40 to be coated with adhesive.

[0102] It should be understood that in this embodiment, the support 10 serves as the working platform of the adhesive application device 1, which can be used to place the product 40 to be adhesiveped. The first robotic arm 20 controls the movement and adhesive dispensing of the adhesive application component 30 to apply adhesive to the product 40. In some embodiments, the first robotic arm 20 can be a standard six-axis robotic arm, capable of linear movement along the X, Y, and Z axes, and rotational movement around the X, Y, and Z axes. For example, the X, Y, and Z axes are respectively... Figure 10 The X, Y, and Z directions are shown.

[0103] During the glue application process, the application direction can be switched between the X and Y directions, that is, as shown below. Figure 2 The adhesive application direction X1 shown can be the same as the X direction, or it can be the same as the Y direction. For example, after the product 40 to be coated is placed on the support 10, the first robotic arm 20 drives the adhesive application component 30 to move along the X direction or along the Y direction, thereby completing the adhesive application to the area to be coated.

[0104] In some embodiments, such as Figure 10As shown, the adhesive coating equipment may also include a weighing and detection mechanism 50, which measures the weight of the adhesive to detect whether the dispensing mechanism 31 is operating normally. It should be understood that when the weighing and detection mechanism 50 needs to weigh the adhesive, the first robotic arm 20 controls the adhesive coating assembly 30 to move to the weighing platform, and the nozzle 315 dispenses a fixed length of adhesive onto the weighing and detection mechanism 50. The weighing and detection mechanism 50 measures whether the weight of this section of adhesive is within the specified weight range, thereby detecting whether the amount of adhesive dispensed by the nozzle 315 meets the requirements. On the one hand, by automatically weighing the adhesive through the weighing and detection mechanism 50, the adhesive coating quality of the equipment can be maintained stably, improving the accuracy of automatic adhesive coating. On the other hand, different dispensing amounts can be set for different products to be coated, thereby improving the compatibility of the equipment with different products. The weighing and detection mechanism 50 can weigh the first piece of adhesive before coating begins, or it can automatically weigh the current adhesive at intervals during the coating process. The weighing interval during the glue application process can be flexibly set to meet different glue application precision requirements. For example, automatic weighing can be performed every hour or half an hour.

[0105] In some embodiments, such as Figure 10 As shown, the adhesive application equipment may also include a fixing component 60, such as... Figure 12 As shown, Figure 12 A schematic diagram of the structure of the fixing component according to an embodiment of this application is shown, for example, Figure 12 It shows Figure 10 A schematic diagram of the fixing component 60 in the adhesive application equipment 1 shown. Figure 12 As shown, the fixing assembly 60 includes a tray 61 and a cylinder 62. The tray 61 is placed on the bracket 10, and the product 40 to be glued is fixed on the tray 61. The cylinder 62 is located on the side of the tray 61 away from the product 40 to be glued. The cylinder 62 moves along the thickness direction of the tray 61, causing the tray 61 to separate from or contact the bracket 10. It should be understood that the thickness direction of the tray 61 can be... Figure 12The Z-direction is shown in the diagram. The positional relationship between the tray 61, the product to be glued 40, and the cylinder 62 can be such that the cylinder 62, tray 61, and product to be glued 40 are arranged sequentially along the Z-direction, with the tray 61 located between the product to be glued 40 and the cylinder 62. When the cylinder 62 is not in operation, the tray 61 is placed on the support 10, with a certain distance between the cylinder 62 and the tray 61. When it is time to apply glue to the product to be glued 40, the cylinder 62 moves towards the tray 61 along the Z-direction and connects and fixes itself to the tray 61, while simultaneously driving the tray 61 to continue moving along the Z-direction, causing the tray 61 to separate from the support 10, and the glue application assembly 30 begins to apply glue to the product to be glued 40; after the glue application assembly 30 completes the glue application, the cylinder 62 moves away from the tray 61 along the Z-direction, causing the tray 61 to be placed back on the support 10, and the cylinder 62 continues to move until it can be separated from the tray 61, at which point the cylinder 62 returns to its original position, with a certain distance between the cylinder 62 and the tray 61.

[0106] It should be understood that after the cylinder 62 contacts the tray 61, the cylinder 62 and the tray 61 are relatively fixed, so that the tray can remain stationary during the glue application process, thereby keeping the product 40 to be glued on the tray in a static state. The fixing method between the cylinder 62 and the tray 61 can include one or more of the following: snap-fit ​​fixing, magnetic fixing, suction cup fixing, and positioning pin fixing. By moving back and forth along the thickness direction of the tray 61, the cylinder 62 realizes the separation and contact between the tray 61 and the bracket 10, which can automatically complete the fixing operation of the product to be glued, reduce labor costs, and improve the glue application efficiency of the glue application equipment.

[0107] In some embodiments, a conveyor belt may also be provided on the support 10, and a tray 61 is placed on the conveyor belt. A cylinder 62 moves towards the tray 61, connecting the tray 61 to the cylinder 62 and separating it from the conveyor belt on the support 10. Alternatively, the cylinder 62 moves away from the tray 61, bringing the tray 61 into contact with the conveyor belt on the support 10 and separating it from the cylinder 62, so that the tray 61 moves with the conveyor belt. The product 40 to be coated on the tray 61 can move along with the tray 61 on the conveyor belt. The product 40 can be moved from other stations to the coating station and from the coating station to other processing stations, improving the automation level of the coating equipment.

[0108] It should be understood that a stop can be provided on the support 10 so that when the tray 61 moves with the conveyor belt to the position where glue needs to be applied or other processing positions, the stop can stop the tray 61 and separate the tray 61 from the conveyor belt via the cylinder 62, so that the glue application assembly 30 can apply glue to the product 40 to be glued on the tray 61. For example, as Figure 12As shown, a second stop 12 and a first stop 11 are sequentially arranged on the support 10 along the conveyor belt's moving direction. The first stop 11 can move along the thickness direction of the tray 61 to prevent the tray 61 from moving with the conveyor belt. The second stop 12 is used to prevent the tray 61 from springing back after it stops moving with the conveyor belt. It should be understood that the thickness direction of the tray 61 can be... Figure 12 The Z-direction shown means that the first stop 11 can move along the Z-direction, and the conveyor belt can move in the following direction: Figure 12 In the X direction shown, the direction in which the tray 61 is rebounded is opposite to the direction of the conveyor belt movement. The first stop 11 can be positioned on the bracket 10 corresponding to the glue application assembly 30. Before the tray 61 carrying the product 40 to be glued moves to the glue application position, the first stop 11 moves upward in the Z direction, stopping the tray 61 from continuing to move after it reaches the position of the first stop 11. The second stop 12 prevents the tray 61 from rebounding if it suddenly stops, thus restricting movement on both sides of the tray 61 along the conveyor belt movement direction. The first stop 11 and the second stop 12 can quickly bring the tray 61 to a stop, allowing the cylinder 62 to fix the tray 61 and separate it from the conveyor belt, thereby enabling the glue application assembly 30 to apply glue to the product 40.

[0109] In some embodiments, the distance between the first stop 11 and the second stop 12 along the conveyor belt movement direction is greater than or equal to the dimension of the tray 61 along the conveyor belt movement direction, and less than a first threshold. It should be understood that the conveyor belt movement direction can be... Figure 12 In the X direction, the distance between the first stop 11 and the second stop 12 should be greater than or equal to the dimension of the pallet 61 in the X direction, so that the pallet 61 can be stopped in time when it reaches the target position. The first threshold can be slightly larger than the dimension of the pallet 61 in the X direction, so that after the pallet 61 is blocked by the first stop 11, the second stop 12 can effectively prevent the pallet 61 from bouncing back too far, and can quickly stop the pallet 61 at the target position.

[0110] In some embodiments, such as Figure 10As shown, the adhesive application equipment may further include a second robotic arm 70 and a plasma cleaning mechanism 80. The second robotic arm 70 is disposed on one side of the support 10, and the plasma cleaning mechanism 80 is connected to the second robotic arm 70. The second robotic arm 70 controls the plasma cleaning mechanism 80 to clean the area of ​​the product 40 to be coated with adhesive. It should be understood that before applying adhesive to the product 40, the surface 401 to be coated with adhesive can also be cleaned by the plasma cleaning mechanism 80. Cleaning the surface 401 with the plasma cleaning mechanism 80 removes dust, oil, moisture, and other impurities, improving the adhesive's bonding performance. Moreover, cleaning the surface 401 keeps it clean, ensuring good contact between the adhesive and the product 40, thereby improving bonding strength and coating quality.

[0111] In some embodiments, the second robotic arm 70 can be a four-axis robotic arm, capable of linear movement along the X, Y, and Z axes, and also capable of rotational movement along the Z axis. For example, the X, Y, and Z axes are respectively... Figure 10 The X, Y, and Z directions are shown.

[0112] It should be understood that the second robotic arm 70 can be disposed on either side of the support 10. For example, the second robotic arm 70 can be disposed on the same side of the support 10 as the first robotic arm 20, or the second robotic arm 70 and the first robotic arm 20 can be disposed on different sides of the support 10. The first robotic arm 20 and the second robotic arm 70 can be disposed at different positions on the support 10. For example, the second robotic arm 70 and the first robotic arm 20 can be sequentially disposed on one side of the support 10 along the conveyor belt movement direction. The conveyor belt movement direction can be as follows: Figure 10 The X direction is shown. The second robotic arm 70 is positioned upstream of the conveyor belt, and the first robotic arm 20 is positioned downstream of the conveyor belt. Thus, the tray 61, moving with the conveyor belt, can carry the product 40 to be coated with adhesive, which sequentially passes through the plasma cleaning mechanism 80 and the adhesive coating assembly 30. First, it reaches the plasma cleaning mechanism 80 for cleaning the surface 401 to be coated, and then it reaches the adhesive coating assembly 30 for applying adhesive to the surface 401. The adhesive coating equipment can directly transfer the cleaned product to the adhesive coating assembly for coating without manual operation, saving time and labor costs and improving the coating efficiency.

[0113] In some embodiments, such as Figure 10As shown, the adhesive coating equipment may also include a cleaning and testing mechanism 91, which is used to detect whether the plasma cleaning mechanism 80 has cleaned properly. For example, a test sample is placed on the cleaning and testing mechanism 91. The second robotic arm 70 controls the plasma cleaning mechanism 80 to move to the area where the cleaning and testing mechanism 91 is located. The plasma cleaning mechanism 80 cleans the test sample placed on the cleaning and testing mechanism 91 and detects parameters such as surface tension, roughness, gloss, and detergency of the cleaned test sample. For example, if the surface tension of the test sample meets a preset threshold, the second robotic arm 70 controls the plasma cleaning mechanism 80 to clean the product 40 to be coated; otherwise, the cleaning parameters of the plasma cleaning mechanism 80 are adjusted to continue testing using the test sample.

[0114] It should be understood that the glue coating equipment has a control unit, and through a communication interface, the various parts of the glue coating equipment, such as the first robotic arm 20, the glue coating component 30, the weighing and detection mechanism 50, the fixing component 60, the second robotic arm 70, and the plasma cleaning mechanism 80, can exchange data and control each part through a fieldbus.

[0115] In some embodiments, such as Figure 10 As shown, the adhesive coating equipment also includes an arch frame 92, which can be used to store various types of wires within the equipment. For example, the arch frame 92 has hooks on which various wires can be hung. On one hand, the arch frame 92 prevents the wires from being stepped on or impacted, and prevents them from contacting the ground or accumulating water, reducing the risk of electric shock and the possibility of short circuits. On the other hand, suspending the wires in the air via the hooks helps dissipate heat and prevents overheating that could damage them.

[0116] In some embodiments, one or more fixing components 60 may be provided, each placed at a different process location. For example, Figure 10As shown, the fixing component 60 may include a first fixing component 601 and a second fixing component 602. The first fixing component 601 is disposed on the support 10 near the first robotic arm 20, and the second fixing component 602 is disposed on the support 10 near the second robotic arm 70. Multiple first stoppers 11 and second stoppers 12 may also be provided. The first stopper 11 and second stopper 12 may be disposed on the support 10 where the first fixing component 601 is located, and / or the first stopper 11 and second stopper 12 may be disposed on the support 10 where the second fixing component 602 is located. The first fixing component 601 may be disposed on the support 10 near the first robotic arm 20. When the product 40 to be glued arrives at the position corresponding to the first fixing component 601 along with the tray 61, the first stopper 11 and second stopper 12 cause the tray 61 to stop moving in time. The cylinder 62 then actuates to fix the tray and move the tray to the required glue application position of the glue application component 30. The second fixing component 602 can be set at the bracket 10 near the second robotic arm 70. When the product 40 to be coated with glue arrives at the position corresponding to the second fixing component 602 along with the tray 61, the first stop 11 and the second stop 12 cause the tray 61 to stop moving in time. The cylinder 62 is activated to fix the tray and move the tray to the required cleaning position of the plasma cleaning mechanism 80. By setting fixing components at both the cleaning and glue application positions of the product to be coated with glue, the cleaning and glue application of the product to be coated with glue can be completed fully automatically, improving the automation level of the glue coating equipment and further improving the glue coating efficiency of the glue coating equipment.

[0117] In some embodiments, such as Figures 1 to 12 As shown, the automatic cleaning and adhesive application method of the adhesive application equipment 1 may include the following steps:

[0118] Step 1: The product 40 to be coated with adhesive is fixed on the tray 61, which is placed on the conveyor belt on the support 10 and moves with the conveyor belt. When the tray 61 reaches the area where the plasma cleaning unit 80 is located, the first stop 11 on the support in that area moves upward in the Z direction and works together with the second stop 12 to stop the tray 61 from moving. The cylinder 62 of the second fixing component 602 moves in the Z direction to separate the tray 61 from the conveyor belt and fix the tray 61. At this time, the product 40 to be coated with adhesive is located at the cleaning station.

[0119] Step two: The second robotic arm 70 controls the plasma cleaning mechanism 80 to clean the adhesive-coated surface 401 of the product 40. After cleaning, the second robotic arm 70 resets, the cylinder 62 of the second fixing component 602 moves along the Z direction to reset the tray 61, the tray 61 is placed back on the conveyor belt, the first stop 11 moves downward along the Z direction to reset, and the tray 61 continues to move with the conveyor belt.

[0120] Step 3: When the tray 61 reaches the area where the glue application component 30 is located, the first stop 11 on the bracket in that area moves upward in the Z direction and works together with the second stop 12 to stop the tray 61 from moving. The cylinder 62 of the first fixing component 601 moves in the Z direction to separate the tray 61 from the conveyor belt and fix the tray 61. At this time, the product 40 to be glued is located at the glue application station.

[0121] Step four: The glue dispensing mechanism 31 and the visual inspection mechanism 32 perform glue application and glue quality inspection on the product to be glued. After the glue application is completed, the glue application assembly 30 moves a certain distance away from the glued product. The glue receiving mechanism 34 moves the first moving mechanism 342 and the second moving mechanism 343, causing the glue receiving box 341 to move below the glue nozzle 315, so that the glue remaining on the glue nozzle 315 falls into the glue receiving box 341.

[0122] Step 5: After the glue application is completed, the glue application mechanism 34 is reset. At the same time, the cylinder 62 of the first fixing component 601 moves along the Z direction to reset the tray 61. The tray 61 is then placed back on the conveyor belt. The first stop 11 moves downward along the Z direction to reset, and the tray 61 can continue to move with the conveyor belt.
